Crashes don't surprise me under these circumstances. What would I be looking for on the box/datasheet/whitepaper to find if a card supports sharing? Is there an acronym? Looking at the Intel Pro 100+ (which IIRC someone claimed supported sharing) on Intel's site (http://www.intel.com/network/connectivity/products/pro100_dsktop.htm) nothing really stands out and says "I support sharing". The only thing I see that even looks remotely interesting is the claim that it supports INTA, which seems a little odd since AFAIK the 4 regular PCI interrupts are INTA-INTD, so this looks like it's claiming to suppport interrupts. -- \ |_ _|__ __|_ \ __| Jason Andresen jandrese@mitre.org |\/ | | | / _| Network and Distributed Systems Engineer _| _|___| _| _|_\___| Office: 703-883-7755 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
